Trial Outcomes & Findings for Aripiprazole Augmentation of SSRI Therapy in Treatment Refractory Depression (NCT NCT00608543)

NCT ID: NCT00608543

Last Updated: 2012-10-26

Results Overview

The SOC is part of the CAmbridge Neuropsychological Test Automated Battery (CANTAB) and is an executive function task based on the Tower of London test that assesses spatial planning for problems with 2, 3, 4, or 5 moves. The Mean Initial Thinking Time for 3-move problems is the time (in milliseconds)taken to plan a problem solution for trials requiring 3 moves. Higher numbers indicate poorer performance. Time reported is the difference between baseline and 6 weeks post-treatment.

PRIMARY outcome

Timeframe: baseline and 6 weeks

Population: Completers; due to fact that testing occurred at pre- and post-intervention; mean represents difference between pre- and post-intervention

The SOC is part of the CAmbridge Neuropsychological Test Automated Battery (CANTAB) and is an executive function task based on the Tower of London test that assesses spatial planning for problems with 2, 3, 4, or 5 moves. The Mean Initial Thinking Time for 3-move problems is the time (in milliseconds)taken to plan a problem solution for trials requiring 3 moves. Higher numbers indicate poorer performance. Time reported is the difference between baseline and 6 weeks post-treatment.

PRIMARY outcome

Timeframe: baseline and 6 weeks

Population: Completers because data were collected pre- and post-treatment

The SWM task is part of the CANTAB neruopsychological test battery and is an executive function task assessing retention and manipulation of items in working memory, with the ability for assessment of perseverative (redundant) errors. Between errors are times the subject revisits a box in which a token was previously found; errors are calculated for 4-, 6-, and 8-box trials. Higher numbers indicate poorer performance. Errors reported are the difference between baseline and 6 weeks post-treatment.

PRIMARY outcome

Timeframe: baseline and 6 weeks

Population: Completers; due to fact that testing occurred at pre- and post-intervention; mean represents difference between pre- and post-intervention

The SWM task is part of the CANTAB neruopsychological test battery and is an executive function task assessing retention and manipulation of items in working memory, with the ability for assessment of perseverative (redundant) errors. The Strategy score represents the number of times a participant begins a search with the same box for 6- and 8-box problems. Minimum score is 8 and maximum score is 56. Higher numbers indicate poorer performance. Score reported is the difference between baseline and 6 weeks post-treatment.

SECONDARY outcome

Timeframe: 6 weeks

Population: Study completers who completed the Q-LES-Q pre- and post-intervention; mean represents mean difference from pre- to post-intervention

The Q-LES-Q general activities is designed to measure subjective satisfaction and enjoyment, as opposed to function, in various domains including physical health, feelings, work, household duties, school/course work, leisure time activities, social relations, and general activities. The raw score is converted into a percent of the maximum possible score and range from 0 to 100. Higher scores indicate greater enjoyment and satisfaction.

SECONDARY outcome

Timeframe: 6 weeks

Population: Study completers who completed the HRSD pre- and post-intervention; mean represents mean difference from pre- to post-intervention

The HRSD 17-item scale is a clinician-administered rating scale designed to assess the severity of symptoms in patients diagnosed with depression. Scores range from 0 to 52, with higher scores indicating higher levels of depression severity.
